摘要:
A parison, as a precursor of a container, composed at least of a thermoplastic resin (resin A) and another thermoplastic resin having excellent gas-barrier property (resin B) and containing a multilayered resin layer at least in an intermediate layer between an outermost layer and an innermost layer each composed of resin A at parts other than the open end part of the mouth portion of the parison, or wholly in the parison, said multilayered resin layer being formed by using an injection-molding machine equipped with a static mixing-stirring device provided in a nozzle portion of an injection cylinder, or in a mold, or in a resin flow passage between the nozzle portion and a mold, and injecting the resins A and B through the static mixing-stirring device so that flows of the resins A and B are divided in a plurality of thin layers parallel to the flowing direction; and a process for production thereof. A container obtained by biaxially stretching and blow-molding the said parison has excellent transparency, gas-barrier property and mechanical strength.

The invention relates to labelling a container. A container (10), for example a packaging for eggs, fruit or the like, has a lid portion (12) hinged to a base portion (11). The lid (12) or hinge (13) has a flat internal surface (15) defining an area to which a label (23) is to be applied. For removably holding the label in position a plurality of projections (22) are disposed on the periphery of that area, which projections are moulded integrally with the container and extend in overlapping, spaced relation with the area of the surface to which the label is to be applied.

Disclosed is an airtight container comprising a container body with an opening opened upward, and a cover for opening and closing the opening, the container body comprising a bottom, a wall extended upward from an edge of the bottom, and a cover contact portion provided at a top portion of the wall to come into contact with the cover, the cover comprising a cover body with glass centrally positioned, and a cover seal of which an inward side is coupled around the cover body and an outward side is coupled to the wall and the cover contact portion to maintain sealing between the container body and the cover, and the cover seal comprising a sealing body coupled to surround the cover body, a container contact portion provided beneath the sealing body and shaped corresponding to the cover contact portion to come into contact with the cover contact portion, a sealing skirt extended downwards from an inward plate surface of the container contact portion, and a horizontal rib bent outwards from an end portion of the sealing skirt and elastically transformable for sealing between the container body and the cover by coming into contact with the wall while the opening is closed. Thus, the airtight container is prevented from a pup-up phenomenon that the cover is separated from the container body by internal pressure, has a simple structure, is easy to use, and includes fewer parts.

A product package comprises a box (170), and a two-way humidity control device (150) for controlling headspace relative humidity in the product package. The humidity control device contains a humidity control agent for controlling the relative humidity (RH) within a packaged consumer product, such as a food, pharmaceutical, herb, or any other suitable consumer product. The humidity control device is integrated with the product packaging. For example, a base layer of the humidity control device comprises an inner wall of the box. A permeable layer of the humidity control device comprises a material permeable to water vapor and impermeable to aqueous solutions; and the humidity control agent is arranged between the base layer and permeable layer. The permeable layer is coupled to the inner surface of the box by an adhesive.

A compression moulding tool for manufacturing a fibrous pulp tray (600) having a floor portion (602) and walls (604) extending from the floor portion. The tool comprises a first female mould element (102) comprising a plurality of first recessed portions (112), a water permeable filter (202) arranged in the first female mould element and configured to follow the surface of the female mould element, a second female mould element (104) comprising a plurality of second recessed portions (306) at locations corresponding to the first recessed portions and smaller than the first recessed portions, and a male mould element (106) configured to press against the first and second female mould elements to compress a fibrous pulp product located therebetween, the male mould element having a smooth surface profile at locations corresponding to the first and second recessed portions of the first and second female mould.
